Moderate
Avalanche Summary
Multiple small to large wet loose and glide slab avalanches (Size 1 to 2.5) continue to be reported in the Coquihalla and Fraser Valley area from the recent warming period.
Thank you to all our recent MIN submissions, we appreciate you!
Snowpack Summary
In the alpine, new snow covers a variably breakable crust caused by recent strong winds and above freezing temperatures. At lower elevations, the top 10-20 cm of snow is moist.
In the Coquihalla area, overnight clearing may have frozen the wet surface into a crust.
The mid and lower snowpack contains various old crusts and is generally well-settled and stable.

Terrain and Travel Advice
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Be carefull with sluffing in steep terrain, especially above cliffs and terrain traps.
- The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
